DL.3 S-Video Input Not Working

I have two DL.3's, and am trying to input an S-Video signal into both. The 1st unit projects the S-video signal fine, but the 2nd unit does not. The DMX settings on both units are the same.

On the unit not projecting s-video, I see a bluish projected image. I have done all kinds of troubleshooting from changing camera, cable, resetting the server, going back to default setting on the instrument all with no luck.

Is it a hardware problem or a software problem?

Any suggestions?
